1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectivesTo evaluate the effectiveness of in-vivo dosimetry (IVD) utilizing an electronic portal imaging device (EPID) in conjunction with EPIgray

methodsUsing cross-sectional analysis, data were collected from the linear accelerator of twenty patients undergoing (H&N) radiotherapy treatments using the Volumetric Modulated Arc Therapy (VMAT) modality from June 2019 to October 2023 at Gleneagles Hospital Penang, Penang, Malaysia. EPIgray

resultsThe percentage difference between the reconstructed doses and planned doses (ΔD%) for patients ranged from (1.96) to (-11.1), and the results showed that 60% of the patients' doses were within the tolerance range (±5%). The phantom study resulted in a percentage dose difference (ΔD%) of -1.73%, and this was established as a benchmark for accuracy.

conclusionThe study proves that using EPID-based in-vivo dosimetry with EPIgray
